DUAL TONE AND POLARITY SWITCH
LNB MULTIPLEX CONTROLLER
DEVICE DESCRIPTION
The ZLNB2006/09/10 group of dual polarisation and
tone switch controller are part of a wide range of
satellite receiver LNB support circuits available from
Zetex. Each part features two completely independent
channels, each providing logic outputs to control LNB
polarisation selection, local oscillator selection and the
ZLNB2009/10 also provides downfeed disable. They
are intended for use in Twin Universal and Quad LNBs,
replacing many discrete components to save both
manufacturing cost and PCB size whilst improving
reliability.
Universal LNB local oscillator selection is achieved by
detection of a low level AC voltage superimposed on
the polarisation control voltage. To facilitate this
function, the ZLNB2006/09/10 includes a separate tone
detector for each channel. Full control of detector
bandwidth and sensitivity is provided using two
external resistors and capacitors. In the ZLNB2006/9,
additional control of tone switch delays is provided to
assist with the rejection of low frequency control
signals intended for other systems.
Polarisation switch and tone detector outputs can
source and sink 10mA making them suitable to drive
TTL and CMOS logic, pin diodes and IF-amp supply
switching.
T h e tw o pol a ri s at i on c ont r ol i nput s o f t h e
ZLNB2006/09/10 have a nominal threshold of 14.75V.
The threshold is temperature compensated to
minimise drift. Each features a low and stable input
current that enables transient protection to be
achieved with the addition of only a single resistor per
channel.
The ZLNB2006/09/10 operates from a single supply
which can be anything from 5-10V. Their quiescent
current is typically only 6mA and this does not change
significantly with load or logic state. They are available
in the space saving QSOP16 or QSOP20 surface mount
package.
Multi Feed LNBs can be called to operate with one or
more of their controlling receivers powered
down/disconnected, with attendant cable mismatch
problems. To ease design for this situation, each
polarisation input of the ZLNB2009/10 has a second
threshold set at 9.5V. An input voltage below this
threshold indicates “receiver not present”, switching
the relevant control channels high. This logic output
can be used to disable the associated downfeed driver,
eliminating any problems due to cable mismatch.

Additionally the front end bias requirements of the LNB
are provided by ZNBG4000 or ZNBG6000 offering a
very efficient and cost effective solution
The following diagram shows a typical block diagram
for a twin universal LNB design. The ZLNB2006/09/10
group of devices provides the two polarity and two
tone switches required to decode the two independent
receiver feeds. The ZLNB2009/10 devices are also able
to detect the absence of receiver connection to either
port of the LNB providing all outputs to go high hence
disabling of the port. This allows the avoidance of
unwanted signal reflections from an unterminated
down feed cable.

FURTHER INFORMATION
3) The ZLNB2006/9 includes the circuitry necessary to
detect the presence of 22kHz tones modulated on
either of two supply inputs to the LNB. The main
elements of the detectors in each channel are an
op-amp enabling the construction of a Sallen Key filter,
a rectifier/smoother and a comparator. Full user
control is given over the centre frequency and
bandwidth of the filter using two external resistors and
capacitors (one of these resistors shares the function of
overvoltage protection of the corresponding Vpol pin,
i.e. the 10k referenced in note 1). The comparator
circuit utilises no external components. The presence
of a 22kHz tone applied to pin Fin1 or Fin2 switches the
corresponding output Yn1 or Yn2 high. Pins Crec1 and
Crec2 on the ZLNB2006/9 make accessible the outputs
of the tone switch rectifiers and provides a means of
controlling tone switch delays. Significant switching
delays may be necessary to avoid incorrect operation
in the presence of unwanted interference (e.g.
switching tones intended for other signalling systems).
For correct operation of the IC, a capacitor and a
parallel connected resistor should be connected
between each Crec pin and ground. The Yout low to
high delays are set solely by the added capacitors at
approximately 22ms/uF. The high to low delays are set
by the time constant of each resistor capacitor
combination at approximately 0.2CR seconds. A
capacitor of 100nF and resistor of 1M⍀ will give a low
to high delay of around 2.2ms and a high to low delay
of 20ms, providing immunity to the 60Hz square wave
signal occasionally used for switching between
multiple LNB units.
1) Inputs VPOL1 and VPOL2 are designed to be wired to
the power inputs of an LNB via high value (10k)
resistors. Input VPOL1 controls a combination of the
Yn1 outputs. Input VPOL2 controls a combination of the
Yn2 outputs. With either input voltage set at or below
14V, one of the corresponding Y0n or Y2n outputs
becomes active dependent upon the presence of a
tone. With either input voltage set at or above 15.5V,
one of the corresponding Y1n or Y3n outputs becomes
active dependent upon the presenence of a tone.
Should the voltage applied to either VPOL input fall
below 9.5V, all outputs on the corresponding output
will go high, otherwise these outputs are as normal.
Any input or output not required may be left
open-circuit.
2) The ZLNB2010 includes the circuitry necessary to
detect the presence of 22kHz tones modulated on
either of two supply inputs to the LNB. The main
elements of the detectors in each channel are an
op-amp enabling the construction of a Sallen Key filter,
a rectifier/smoother and a comparator. Full user
control is given over the centre frequency and
bandwidth of the filter using two external resistors and
capacitors (one of these resistors shares the function of
overvoltage protection of the corresponding VPOL pin,
i.e. the 10k referenced in note 1). The comparator
circuit utilises no external components. The presence
of a 22kHz tone applied to pin Fin1 or Fin2 switches the
corresponding output Yn1 or Yn2 high.
